Answer:

$315.00

Step-by-step explanation:

You'll probably use the equation y=mx+b

so set up the equation as y= 40x + 75

75 is your flat fee and 40 is your hourly pay.

SOLVE FOR "X"

In this question our X is already given to us, "X" is 6

So y= 40(6) + 75

So 40 x 6 = $240

Then add your flat fee of $75

So $315
